Description

Technical Field

[0001] This application relates to the field of paper bag machine technology, specifically a composite conveying mechanism for a paper bag machine. Background Technology

[0002] A paper bag machine is an automated device used to produce paper bags for sale. The raw material is various types of paper. The production process involves first cutting the roll paper into a set size, then conveying it to the forming assembly via a conveying mechanism to complete the forming of the paper bag into a tube, followed by subsequent processes such as bottom card placement, bottom forming, and handle gluing. In existing technologies, the conveying mechanism usually adopts a roller and pressure roller assembly structure. Its advantage is that it is easy to adjust the lateral position of the paper. However, it has the disadvantage of insufficient conveying friction. For example, when conveying UV-coated paper raw materials, the smooth surface of UV-coated paper is prone to slippage during conveying, which can lead to deformation of the paper bag tube and damage caused by overlapping of the target paper in front and behind. Summary of the Invention

[0003] The purpose of this application is to provide a composite conveying mechanism for a paper bag machine to solve the problems in the prior art.

[0004] To achieve the above objectives, this application provides the following technical solution: a composite conveying mechanism for a paper bag machine, including a frame wall plate 1, a front roller group 3 and a rear roller group 2 rotatably disposed between the frame wall plates 1, a pressure roller group 10 disposed above the front roller group 3 and the rear roller group 2, wherein both the front roller group 3 and the rear roller group 2 have multiple rollers arranged in parallel, and further includes:

[0005] The intermediate roller group 4 is located between the front roller group 3 and the rear roller group 2. The intermediate roller group 4 includes several pairs of intermediate rollers arranged in parallel. Each pair of intermediate rollers includes a left half-shaft roller 401 and a right half-shaft roller 402 that are coaxial and spaced apart in the axial direction.

[0006] The housing 6 is located below the left half-shaft roller 401 and the right half-shaft roller 402 at a distance. A guide hole 8 is provided on the upper surface of the housing 6, and a negative pressure interface 7 is provided at the lower end of the housing 6, which communicates with the guide hole 8.

[0007] The last roller of the front roller group 3 and the first roller of the rear roller group 2 have annular grooves 12 formed on the roller corresponding to the position of the box body 6.

[0008] The conveyor belt 11 is wound around the annular groove 12 formed on the last roller of the front roller group 3 and the first roller of the rear roller group 2, and the inner surface of the upper half of the conveyor belt 11 slides against the upper end face of the box 6. The conveyor belt 11 is provided with evenly distributed adsorption holes 9. When the conveyor belt 11 moves, the adsorption holes 9 and the guide holes 8 are alternately aligned to generate an adsorption force on the target paper 19 on the surface of the conveyor belt 11.

[0009] Furthermore, after the conveyor belt 11 is wound inside the annular groove 12, the surface of the conveyor belt 11 is flush with the outer circular surface of the corresponding roller.

[0010] Furthermore, the composite conveying mechanism of the paper bag machine also includes:

[0011] Guide columns 18, having at least two parallel and spaced-apart columns, are connected between the frame wall panels 1 and located below the housing 6;

[0012] The bracket 5 is connected to the bottom of the box 6 and paired with the guide post 18 and sleeved on the guide post 18 to support the box 6.

[0013] Furthermore, the composite conveying mechanism of this paper bag machine also includes an adjusting component for adjusting the tension of the conveyor belt 11, the adjusting component comprising:

[0014] The guide seat 15 is fixedly installed on the frame wall panel 1 and located below one end of the housing 6. The guide seat 15 is provided with a vertical sliding groove 20.

[0015] The slider 16 is slidably fitted within the vertical groove 20;

[0016] The floating guide shaft 14 is rotatably supported by the slider 16;

[0017] The adjusting screw 17 is threaded into the guide seat 15 and rotatably connected to the slider 16 to drive the slider 16 to move along the vertical slide groove 20;

[0018] An auxiliary guide shaft 13 is rotatably mounted on the frame wall panel 1 and located below the other end of the housing 6;

[0019] The lower half of the conveyor belt is wound around the floating guide shaft and the auxiliary guide shaft.

[0020] The beneficial technical effects of this application are as follows: The composite conveying mechanism for paper bag machines provided by this application utilizes a conveyor belt that generates adsorption force, located between the front roller group and the rear roller group, and left and right half-shaft rollers located on both sides of the conveyor belt. The conveyor belt adsorbs and conveys the target paper, while the left and right half-shaft rollers of the intermediate roller group provide auxiliary support in the width direction of the target paper during conveying, thereby achieving stable conveying of the target paper. Since the power of the conveyor belt is directly obtained from the corresponding rollers in the front and rear roller groups, the running speed of the conveyor belt is consistent with the linear speed of the front roller group, the rear roller group, and the intermediate roller group, thus ensuring the stability of the target paper conveying. Furthermore, since it is a composite conveying mechanism that combines local negative pressure adsorption conveying with roller conveying, the required vacuum negative pressure power is small, saving energy while ensuring the conveying effect.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Please see Figure 1-3 A composite conveying mechanism for a paper bag machine includes a frame wall panel 1, a front roller assembly 3 and a rear roller assembly 2 rotatably disposed between the frame wall panels 1, a pressure roller assembly 10 disposed above the front roller assembly 3 and the rear roller assembly 2, both the front roller assembly 3 and the rear roller assembly 2 having multiple rollers arranged in parallel, and also includes an intermediate roller assembly 4, a housing 6, and a conveyor belt 11; wherein...

[0027] The intermediate roller group 4 is located between the front roller group 3 and the rear roller group 2. The intermediate roller group 4 includes several pairs of intermediate rollers arranged in parallel. Each pair of intermediate rollers includes a left half-shaft roller 401 and a right half-shaft roller 402 that are coaxial and spaced apart in the axial direction. The housing 6 is located below the spaced left half-shaft roller 401 and right half-shaft roller 402. The upper surface of the housing 6 is provided with a guide hole 8, and the lower end of the housing 6 is provided with a negative pressure interface 7 that communicates with the guide hole 8. The last roller of the front roller group 3... A ring groove 12 is formed on the first roller of the roller and the rear roller group 2 corresponding to the position of the box body 6; the conveyor belt 11 is wound around the ring groove 12 formed on the last roller of the front roller group 3 and the first roller of the rear roller group 2, and the inner surface of the upper half of the conveyor belt 11 slides against the upper end face of the box body 6. Adsorption holes 9 are evenly distributed on the conveyor belt 11. When the conveyor belt 11 moves, the adsorption holes 9 and the guide holes 8 are alternately aligned to generate an adsorption force on the target paper 19 on the surface of the conveyor belt 11.

[0028] According to the structure provided in this embodiment, the composite conveying mechanism of the paper bag machine provided in this application uses a conveyor belt 11 that can generate adsorption force between the front roller group 3 and the rear roller group 2, and left half-shaft rollers 401 and right half-shaft rollers 402 located on both sides of the conveyor belt 11. The conveyor belt 11 adsorbs and conveys the target paper 19, and the left half-shaft rollers 401 and right half-shaft rollers 402 of the middle roller group 4 provide auxiliary support for the width direction of the target paper 19 during conveying, thereby completing the stable conveying of the target paper 19. Since the power of the conveyor belt 11 is directly obtained from the corresponding rollers in the front roller group 3 and the rear roller group 2, the running speed of the conveyor belt 11 is consistent with the linear speed of the front roller group 3, the rear roller group 2 and the middle roller group 4, thereby ensuring the stability of the conveying of the target paper 19. Furthermore, since it is a composite conveying mechanism composed of local negative pressure adsorption conveying and roller conveying, the required vacuum negative pressure power is small, saving energy while ensuring the conveying effect.

[0029] It is understandable that the front roller group 3 and the rear roller group 2, as well as the left half-shaft roller 401 and the right half-shaft roller 402, can all be synchronized using existing chain drive or gear drive methods. In this embodiment, gear drive is used.

[0030] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 After the conveyor belt 11 is wound inside the annular groove 12, the surface of the conveyor belt 11 is flush with the outer surface of the corresponding roller. According to the structure provided in this embodiment, it is ensured that the target paper 19 can travel smoothly when it arrives on the conveyor belt 11 from the front roller group 3 and is transported to the rear roller group 2 from the conveyor belt 11, avoiding defects such as wrinkles. This is beneficial to improving the conveying stability and reliability of the composite conveying mechanism of this paper bag machine, and further beneficial to improving the conveying efficiency.

[0031] In another embodiment of this application, please refer to [the relevant documentation]. Figures 1 to 3 The composite conveying mechanism of the paper bag machine also includes guide columns 18 and brackets 5. The guide columns 18 have at least two parallel, spaced-apart columns connected between the frame wall panels 1 and located below the housing 6. The brackets 5 are connected to the bottom of the housing 6 and paired with the guide columns 18, and are sleeved on the guide columns 18 to support the housing 6. According to the structure provided in this embodiment, the support of the guide columns 18 and brackets 5 ensures the stability of the housing 6. The brackets 5 can be secured on the guide columns 18 using locking screws or similar structures. The positioning of the housing 6 is completed to improve the conveying stability and reliability of the composite conveying mechanism of the paper bag machine. Here, it can be understood that the adjacent shaft ends of the left half-shaft roller 401 and the right half-shaft roller 402 are rotatably supported by the outer wall of the housing 6. In this way, the adjacent ends of the outer circular surfaces of the left half-shaft roller 401 and the right half-shaft roller 402 can be closer to the two ends of the conveyor belt 11, which is beneficial to effectively support the target paper 19 in the width direction during conveying, thereby improving the conveying quality of the composite conveying mechanism of the paper bag machine.

[0032] In another embodiment of this application, please refer to [the relevant documentation]. Figures 1 to 3 The composite conveying mechanism of the paper bag machine also includes an adjusting component for adjusting the tension of the conveyor belt 11. The adjusting component includes a guide seat 15, a slider 16, a floating guide shaft 14, an adjusting screw 17, and an auxiliary guide shaft 13; wherein...

[0033] The guide seat 15 is fixedly installed on the frame wall plate 1 and located below one end of the housing 6. A vertical slide groove 20 is provided on the guide seat 15. The slider 16 is slidably engaged in the vertical slide groove 20. The floating guide shaft 14 is supported by the slider 16. The adjusting screw 17 is screwed into the guide seat 15 and rotatably connected to the slider 16 to drive the slider 16 to move along the vertical slide groove 20. The auxiliary guide shaft 13 is rotatably installed on the frame wall plate 1 and located below the other end of the housing 6. The lower half of the conveyor belt 11 is wound around the floating guide shaft 14 and the auxiliary guide shaft 13. Here, the rotational connection between the adjusting screw 17 and the slider 16 is usually achieved by providing a smooth rod part at the free end of the adjusting screw 17 and connecting it to the smooth hole, stepped hole, or T-slot structure on the slider 16 through a snap ring or bearing structure.

[0034] According to the structure provided in this embodiment, by adjusting the screw 17, the slider 16 is driven to slide along the vertical groove 20, thereby driving the floating guide shaft 14 to move up and down along the same path, thereby adjusting the tension of the conveyor belt 11 so that the conveyor belt 11 has a suitable adhesion force on the upper surface of the housing 6, ensuring that the vacuum negative pressure introduced by the negative pressure interface 7 can be transmitted to the surface of the conveyor belt 11 to reliably adsorb the target paper 19; the auxiliary guide shaft 13 is used to avoid interference between the conveyor belt 11 and the housing 6, ensuring smooth operation of the conveyor belt 11, which further helps to improve the conveying quality of the composite conveying mechanism of this paper bag machine.
